  • Abstract
    MOSCAPs and MOSFETs of a single-layer thin HfO/sub 2/ gate dielectric with n+ polysilicon gate were fabricated and characterized. Polysilicon process was optimized such that leakage current and equivalent oxide thickness of HfO/sub 2/ remained low. Excellent C-V properties (e.g. low Dit and frequency dispersion) and reliability characteristics were obtained. Reasonable MOSFET quality was also demonstrated.
